Math CentralQuandaries & Queries


Question from aspen, a student:

the perimeter of a rectangle is twice the sum of its length and its width. the perimeter is 40 meters and its length is 2 meters more then twice its width. what is the length

Hi Aspen,

Suppose the width of the rectangle is $w$ meters.

What is twice the width?

The length is 2 meters more than twice the width so what is the length?

What is twice the length plus twice the width?

You know this is 40 meters and hence you can set up an equation and solve for $w.$

I hope this helps,
